In the reactions of alkali-metal salts of triphenylmethane, diphenyl(2-pyridyl)methane, diphenylacetonitrile, ethyl diphenylacetate, 1-methyl-3-phenylidene, 1,3-diphenylindene, 9-tert-butylfluorene, 9-methylfluorene, 9-benzylfluorene, 9-phenylfluorene, 9-methoxycarbonylfluorene, and fluoradene with α,β,β-trifluorostyrene in dimethoxyethane the products from nucleophilic vinyl monosubstitution at the β-carbon atom are formed with quantitative yields.The rate constants of the reactions of the free carbanions and ion pairs were determined for the controlling stage, i.e., the addition of the nucleophiles at the double bond.A good linear correlation was obtained between the rate constants for the reactions of the free carbanions and ion pairs in nucleophilic substitution and nucleophilic addition.
